Will Smith already locked in for two more Independence Day movies?

This has been 14 years in the making, but IESB is reporting that 20th Century Fox has locked Will Smith in for two sequels to Independence Day:

The plan would be to shoot both films back-to-back. Whether the studio opts to go the Matrix route and release the two films six months apart or do like the Pirates of the Caribbean sequels and split them by a year remains to be seen. According to our sources, if all goes according to plan, the sequel(s) could shoot as early as 2011.

Roland Emmerich is expected to direct. Independence Day grossed over $817.4 million worldwide when it was released in 1996.
